FIELD OF THE INVENTION

The present invention relates to the fields of electronics andelectronic technology, and more particularly to connecting apparatuses,rotating shafts and electronic devices.

BACKGROUND

Presently, with the development of electronic information technology,smart electronic devices such as smart phones, tablets, and laptops arewidely spread and expending their range of use; and the appearance ofelectronic devices is becoming more diverse.

Wherein, using a dual structure to change the appearance of theelectronic device is not uncommon in our daily lives. For example, flipphones that mainly comprise a display panel and the operator panel,laptops, hand-held game consoles that comprise an upper screen and abottom screen, etc.

Currently, when an electronic device with a dual structure needs toachieve the synchronous movement of both structures in the same oropposite direction, biaxial synchronous gears are normally used toconnect each body. FIG. 1 illustrates a biaxial synchronous gear systemsuitable for use with the embodiments of the present invention thatrelies on the linkage of crossed helical gears to achieve synchronousmovement, and may comprise an upper gear, a middle gear and a bottomgear in a same arrangement direction, wherein a slim electronic devicemust compress the minimum size of the three gears to lessen the heightof a dual structure electronic device. Since, in practice, electronicdevices require certain strength biaxial synchronous gears based on thequality assurance, achieving a minimum size of the biaxial synchronousgear structure generally becomes a bottleneck in the design of slim andlight type multi-structural electronic devices. It is obvious that inthe prior art the biaxial synchronous gears are adopted to achievesynchronous movement of each component of an electronic device, but theoccupying space is large and the materials are very heavy. Therefore,the prior art cannot solve the technical problem of slim design forelectronic devices.

Moreover, for thin electronic devices, the height of an electric devicein dual structures may be reduced by compressing the size of the threegears of FIG. 1 to the limit. However, as the biaxial synchronous gearstrength depends on the electronic device quality during operation, thesize of the biaxial synchronous gears usually constitutes the bottleneckfor the structure design of thin electronic devices in the multiplestructures. Therefore, as the biaxial synchronous gears in the existingtechnology are used for synchronous motion of all structure parts inelectronic devices, the existence of the intermediate gear leads to atechnical problem restricting further thickness reduction of electronicdevices in the multiple structures.

SUMMARY

Some aspects resolve existing technicalproblems wherein an intermediate gear restricts further thicknessreduction of electronic devices in the multiple structures when thebiaxial synchronous gears in the existing technology are used forsynchronous motion of all structure parts in the electronic devices

In one aspect a connecting apparatus comprises a first shaft, a secondshaft; and at least one pair of connecting strips connecting the firstshaft and the second shaft. As a function of the at least one pair ofconnecting strips, the first shaft and the second shaft achieve asynchronous rotation.

In another aspect an electronic device comprises a first body, a secondbody and a connecting apparatus that includes a first shaft fixed to thefirst body, a second shaft fixed to the second body, and at least onepair of connecting strips connecting the first shaft and the secondshaft. Based on at least one pair of connecting strips, the first bodyand the second body achieve synchronous rotation via the first shaft andthe second shaft.

For example,when the electronic device is specified as an intelligent environmentcontrol system, the first body may be a preset electronic thermometer,and the second body may be the master controlling device of theintelligent environment control system.

In the embodiment of the present invention, to ensure the at least onepair of connecting strips 30 can pull the first shaft 10 and the secondshaft 20 and achieve synchronous rotation, and to ensure the at leastone pair of connecting strips 30 can be wound around the first shaft 10and the second shaft 20, the at least one pair of connecting strips 30should be specified as being made of a flexible plastic material.

In addition, the second shaft 20 further comprisesthe second shaft body 201, wherein, the second shaft body 201 is fixedon the one end of the second fixing body 200. In the specifiedimplementation process, when an external force is applied on the secondbody of the electronic device and drives the second body to rotate, therotation of the second shaft 20 also occurs. Furthermore, in thespecified implementation process, at least one pair of connecting strips30 connects the first shaft body 101 and the second shaft body 201, thusachieving the synchronous rotation of first shaft body 101 and thesecond shaft body 201. In other words, when an external force isapplied, the first body and the second body can achieve a certain anglebetween each other by the rotation of first shaft 10 and the secondshaft 20.

In the embodiment of the present invention, to fix the first shaft 10 tothe first body, the first fixing body 100 has at least one first fixingstructure engaged with the at least one second fixing structure on thefirst body so as to fix the first shaft 10 to the first body.

The at least one pair of connecting strips 30 connects the first shaftconnecting section 1011 and the second shaft connecting section 2011.

In the embodiment of the present invention, to connect the at least onepair of connecting strips 30 between the first shaft connecting section1011 and the second shaft connecting section 2011, in the specifiedimplementation process, at least one first through hole is arranged oneach of the first shaft connecting section 1011; at least one secondthrough hole is arranged on each of the second shaft connecting section2011; and the at least one pair of connecting strips 30 is threadedthrough the at least one first through hole and the at least one secondthrough hole. Certainly, those skilled in the art can further connectthe first shaft connecting section 1011 and the second shaft connectingsection 2011 with at least one pair of connecting strips 30 according tocertain needs.

In the embodiment of the present invention, to achieve synchronousrotation of the first shaft 10 and the second shaft 20, the first pairof the at least one pair of connecting strips 30 comprises the firstconnecting strip 301 and the second connecting strip 302 that isdifferent from the first connecting strip 301; wherein the firstconnecting strip 301 is disposed in the first region along the firstdirection of the axis of the shaft between the first shaft connectingsection 1011 and the second shaft connecting section 2011; and thesecond connecting strip 302 is disposed in the second region along thesecond direction of the axis of the shaft between the first shaftconnecting section 1011 and the second shaft connecting section 2011. Inthe specified implementation process, the shaft axial line is the axialline of the first shaft 10, or the axial line of the second shaft 20.For example, when the first connecting strip 301 is disposed in thefirst region between the first shaft connecting section 1011 and thesecond shaft connecting section 2011 along the counter-clockwisedirection of the axis of the shaft the second connecting strip 302 isdisposed in the second region between the first shaft connecting section10 and the second shaft 20 along the clockwise direction of the axis ofthe shaft. For example, when the first connecting strip 301 is disposedin the first region between the first shaft connecting section 1011 andthe second shaft connecting section 2011 along the counter-clockwisedirection of the axis of the shaft the second connecting strip 302 isdisposed in the second region between the first shaft connecting section10 and the second shaft 20 along the clockwise direction of the axis ofthe shaft. Another example, when the first connecting strip 301 isdisposed in the first region between the first shaft connecting section1011 and the second shaft connecting section 2011 along the clockwisedirection of the axis of the shaft, the second connecting strip 302 isdisposed in the second region between the first shaft connecting section10 and the second shaft 20 along the counter-clockwise direction of theaxis of the shaft.

In the embodiment of the present invention, after the first body and thesecond body are at a closed state under the control of the connectingapparatus, at this time, it has various settings of the first connectingstrip 301 and the second connecting strip 302 of the at least one pairof connection strips 30. The first setting can be specified as: thefirst end of the first connecting strip 301 is fixed at the firstposition of the first shaft connecting section 1011, the second end ofthe first connecting strip 301 is fixed at the second position of thesecond shaft connecting section 2011, the third end of the secondconnecting strip 302 is fixed at the third position of the first shaftconnecting section 1011, the fourth end of the second connecting strip302 is fixed at the fourth position of the second shaft connectingsection 2011; wherein the connection line of the first axis center andthe second axis center of the same end of the first shaft 10 and thesecond shaft 20, intersects with the outer periphery of the first shaftconnection section 1011 at the first position, intersects with the outerperiphery of the second shaft connection section 2011 at the secondposition; wherein the connection lines of the axis centers is specifiedas the line between the first shaft axis center and the second shaftaxis center. And the first connecting strip 301 is wound around theshaft body of the second shaft connecting section 2011 along the firstdirection from the first position to the second position; the secondconnecting strip 302 is wound around the shaft body of the first shaftconnecting section 1011 along the second direction from the fourthposition to the third position. In other words, in the first case, thefirst connecting strip 301 of the at least one pair of connecting strips30 is wound around the shaft body of the second shaft connecting section2011 along the counter-clockwise direction from the first position tothe second position; the second connecting strip 302 of the at least onepair of connecting strips 30 is wound around the shaft body of the firstshaft connecting section 1011 along the clockwise direction from thefourth position to the third position.

In the embodiment of the present invention, in order to ensure theconnecting apparatus can adjust the specific angle between the firstbody and the second body according to the users' needs, in the specifiedimplementation process, after the first body and the second body are ata closed state under the control of the connecting apparatus, the firstangle between the first body and the second body is 0°, and theconnecting state of one of the connecting strips in the connectingapparatus is as shown in FIG. 3. In view from the direction of the axialline of the first shaft 10 and the second shaft 20, the connecting statediagram of the one of the connecting strips of the connecting apparatusis shown as FIG. 4. When an external force is applied on the electronicdevice and drives the first shaft 10 of the connecting apparatus torotate in the first direction, the first connecting strip 301 pulls thesecond shaft 20 to rotate in the second direction of the second shaft20, and the fourth end of the second connecting strip 302 is woundaround the shaft body of the second shaft 20 along the second direction,so that the first angle is adjusted from 0° to the first open angle. Forexample, when an external force is applied on the electronic device anddrives the first shaft of the connecting apparatus to rotate in theclockwise direction, based on the synchronous motion of the firstconnecting strip, the first connecting strip pulls the second shaft 20along the counter-clockwise direction, and in the meantime, the fourthend of the second connecting strip 302 is wound on the shaft body of thesecond shaft 20 along the counter-clockwise direction, so that the firstangle is adjusted from 0° to any nonzero angle.

In the embodiment of the present invention, in order to ensure theconnecting apparatus can adjust the specific angle between the firstbody and the second body according to the users' needs. In the processof adjusting the angle between the first body and the second body by theconnecting apparatus driven by the external force, the detailedconnecting state of at least one pair of the connecting strip 30 on theshaft body is as follows:

After the first body and the second body are at a closed state under thecontrol of the connecting apparatus, the angle between the connectionline of the first position and the first axis center and the connectionline of the axis centers is 0. When an external force is applied on theelectronic device and drives the first shaft 10 of the connectingapparatus to rotate in the first direction, the first end of the firstconnecting strip 301 is wound around the shaft body of the first shaftconnecting section 1011 from the first position to the length of 1/N ofthe circumference of the shaft along the first direction, adjusting theangle between the connection line of the first position and the firstaxis center and the connection line of the axis centers from 0° to(2π/N). Based on the first connecting strip 301 that connects the firstshaft 10 and the second shaft 20, the first shaft 10 and the secondshaft 20 will achieve synchronous rotation. In this case, the second endis wound around the shaft body of the second shaft connecting section2011 from the second position to the length of 1/N of the circumferenceof the shaft along the second direction, and the angle between theconnection line of the second position and the second axis center andthe connection line of the axis centers is adjusted from 0° to (2π/N),so that the first angle between the first body and the second body isadjusted from 0° to (4π/N); the third end of the second connecting strip302 is wound around the shaft body of the first shaft connecting section1011 from the third position to the length of 1/N of the circumferenceof the shaft along the first direction, the fourth end of the secondconnecting strip is wound around the shaft body of the second shaftconnecting section 2011 from the fourth position to the length of 1/N ofthe circumference of the shaft along the second direction. The firstconnecting strip 301 and the second connecting strip 302 are tied in theopposite direction between the first shaft 10 and the second shaft 20,in the specified implementation process; therefore, when the first endof the first connecting strip is wound around the shaft body of thefirst shaft body 101 from the first position to the length of ½ of thecircumference of the shaft along the counter-clockwise direction, thethird end of the second connecting strip is wound off the shaft body ofthe first shaft body 101 from the third position to the length of ½ ofthe circumference of the shaft along the counter-clockwise direction.Because of the synchronous motion of the same connecting strip, it ishereby not necessary to repeat the winding state of the second end ofthe first connecting strip 301 and the fourth end of the secondconnecting strip 302 on the second shaft 201.

In the embodiment of the present application, an external force appliedon the electronic device can drive the adjustment that changes the anglebetween the first body and the second body to an arbitrary angle.Herein, it is specified as the explanation of adjusting the anglebetween the first body and the second body from 0° to 180° that finallyaccomplishes the adjustment of shifting the closed mode to the tabletmode of a laptop. When an external force is applied on the electronicdevice and drives the first shaft 10 of the connecting apparatus torotate in the first direction, the first end of the first connectingstrip 301 is wound around the shaft body of the first shaft connectingsection 1011 from the first position to the length of ¼ of thecircumference of the shaft along the first direction, and the anglebetween the connection line of the first position and the first axiscenter and the connection line of the axis centers is adjusted from 0°to 90°; the second end is wound around the shaft body of the secondshaft connecting section 2011 from the second position to the length of¼ of the circumference of the shaft along the second direction, and theangle between the connection line of the second position and the secondaxis center and the connection line of the axis centers is adjusted from0° to 90°, so that the first angle between the first body and the secondbody is adjusted from 0° to 180°. FIG. 5 is a connecting state diagramof the connecting apparatus after the adjustment.

In the specified implementation process, while the first body and thesecond body is a nonzero angle, the connecting state of the connectingapparatus when adjusting the angle between the first body and the secondbody to 0° of the closed mode, herein, is specified as the explanationof adjusting the angle between the first body and the second body from180° to 0° that finally accomplishes the adjustment of shifting thetablet mode to the closed mode of a laptop. After the first body and thesecond body are at an open state under the control of the connectingapparatus, and the angle between the first body and the second body is180°, when an external force is applied on the electronic device anddrives the first shaft 10 of the connecting apparatus to rotate in thesecond direction, the third end will adjust the angle between theconnection line of the third position and the first axis center and theconnection line of the axis centers from 90° to 0°; the secondconnecting strip 302 pulls the second shaft 20 to rotate in the firstdirection, the fourth end adjusts the angle between the connection lineof the fourth position and the second axis center and the connectionline of the axis centers from 90° to 0°. In other words, after theelectronic device is in tablet mode, when closing the electronic devicein the clockwise direction, the first shaft turns 90° clockwise, and thesecond shaft turns 90° counter-clockwise, so that the angle between thefirst body and the second body is adjusted from 180° to 0°; and finallythe electronic device is adjusted from tablet mode to the closed mode.In this case, the second end of the first connecting strip 301 is woundaround the shaft body of the second shaft connecting section 2011 fromthe second position to the length of ½ of the circumference of the shaftalong the first direction.

In the embodiment of the present invention, it can be based on the sameinventive concept of adjusting the angle between the first body and thesecond body of the electronic device to any angle, but it is notnecessary repeat it herein.

In the embodiment of the present invention, in order to fix the firstconnecting strip 301 to the specific position on the first shaft 10 andthe second shaft 20, In the specified implementation process, the firstthrough hole is arranged at the first position, and the second throughhole is arranged at the second position, so that the first end of thefirst connecting strip is penetrated at the first position and thesecond end of the first connecting strip is penetrated on the secondposition. Certainly, those skilled in the art can further fix each endof the at least one pair of connecting tape 30 on the first shaft andthe second shaft by other methods, but it is not necessary repeat themherein.

In the embodiment of the present invention, in order to avoid theslipping of the at least a pair of connecting strip 30 affecting theconnection and causing malfunction of the connecting apparatus duringthe process of synchronous rotation of the first body and the secondbody driven by the connecting apparatus, in the specified implementationprocess, at least one first groove on each first shaft connectingsection 1011 should be carved; at least one second groove on each secondshaft connecting section 2011 should be carved; and at least one pair ofconnecting strips 30 should be placed in the relevant grooves. In thespecified implementation process, the grooves can be carved on only thefirst shaft 10 or on the second shaft 20, and further can be carved onthe first shaft 10 and the second shaft 20 simultaneously. When thereare a plurality of grooves on the shaft bodies of the first shaft 10 andthe second shaft 20, the connecting strips can be placed in one or moregrooves. In the specified implementation process, those skilled in theart can make specific settings according to certain needs, but it is notnecessary repeat them herein.

The term “and/or” herein is only an incidental relation describing theinstanced objects and it indicates the possibility of three relations,for example, A and/or B can express the three conditions: A separatelyexists; both A and B exist at the same time; and B separately exists. Inaddition, the character “/” herein generally indicates the “or” relationfor the former and latter instanced objects.

Embodiment 3

Please refer to FIG. 7, wherein the Embodiment 3 of this applicationprovides a rotating shaft comprising:

The first rotating shaft, used to connect the first main body of theelectronic device;

The second rotating shaft, used to connect the second main body of theelectronic device;

At least one transmission belt, sheathed between the first rotatingshaft and the second rotating shaft to synchronize the torques of thefirst and second rotating shafts.

The first main body and the second main body can be two structural partsof an electronic device. The two structural parts can be the parts usedtogether to realize a certain function of the electronic device. Forinstance, the earphone and the main body of a telephone can be usedtogether for dialing and answering functions.

The first main body and the second main body can further be partsrespectively realizing varied functions of the electronic device. Forinstance, when the electronic device is a specific mobile phone withdouble screens, the first main body is one of the screens and the secondmain body is the other.

The first main body and the second main body can be parts withindependent functions of an electronic system. For instance, when theelectronic device is a specific intelligent environment control system,the first main body can be the electronic thermometer arranged in thedefault environment and the second main body can be the master controlequipment only used for the environment control system.

In the embodiments of this application, the transmission belt can beused to replace the intermediate gear between the biaxial synchronousgears When the first rotating shaft rotates, the second rotating shaftis driven by the tension and friction of the transmission belt to rotatewith the first rotating shaft at the same time. On the other hand, sodoes the second rotating shaft during rotation. Similarly, if the firstrotating shaft connected to the first main body rotates, the secondrotating shaft connected to the second main body consequently rotates atthe same time through the transmission belt; in this case, when thefirst main body in the electronic device produces displacement due torotation of the first rotating shaft, the second main body of theelectronic device produces displacement with the first main body due tosynchronous motion. Because the transmission belt can take the mode offitting the edges of the first and second rotating shafts duringimplementation, the synchronous motion of the first and second rotatingshafts remains if the distance is short between the first and secondrotating shafts for the avoidance of the intermediate gear; or theintermediate gear must be used between the first rotating shaft and thesecond rotating shaft during application; therefore, this solution canfurther reduce the thickness of the electronic device.

Meanwhile, the technical solution in the embodiments of this applicationrealizes the synchronous motion of the second rotating shaft only withthe transmission belt but not the gear. Therefore, it is unnecessary touse the complicated parts during production.

The technical solution in the embodiments of the present applicationuses the transmission belt to replace the intermediate gear between thebiaxial synchronous gears to avoid adding the intermediate gear betweenthe first and second rotating shafts, and further reduce the thicknessof the electronic device; and the solution has the following technicaleffects: overcoming the technical defects of restricting themultiple-structure electronic device from further developing with lessweight and smaller thickness, reducing the production cost, furtherlowering the processing complexity and improving the production andprocessing efficiency.

Optionally, the transmission belt is a flexible connecting belt.

As the flexible transmission belt has better ductility than thenonflexible belts, the flexible belt can reduce the damage probabilityunder strong torque during operation and extend the service life of therotating shaft in the technical solution for the embodiments of thisapplication.

On the other hand, as the flexible belt highlights better flexibility,the belt can adapt its shape for various changes of the first and thesecond rotating shafts during operation, for example, when the first andsecond rotating shafts rotate at the asymmetrical speeds under theexternal force, the flexible belt can be adjusted through itsadaptability to such changes to exert the relative action forsynchronization of the first and second rotating shafts.

In addition, as the flexible belt in a certain size can closely fit theouter edges of the first and second rotating shafts, the use of theflexible belt can save the space occupied by the rotating shaft andfurther tuck the rotating shaft structure.

Therefore, the technical solution in the embodiments of this applicationcan reduce the possible damages to the rotating shaft in the embodimentsof this application by use of the flexible belt. When the first rotatingshaft and the second rotating shaft take irregular relative motionsunder external force, it is possible to exert a counterforce through thestrong adaptability for synchronization between the first rotating shaftand the second rotating shaft. Meanwhile, the solution has the technicaleffects of further tucking the rotating shaft structure.

Optionally, the transmission belt is 8-shaped and sheathed between thefirst rotating shaft and the second rotating shaft.

The transmission belt is a figure 8 sheathed between the first andsecond rotating shafts to increase the torque and the consequentialinteraction between the transmission belt and the first and secondrotating shafts. Therefore, the solution can enhance the technicaleffects of sensitivity and fitness between the first and second rotatingshafts during synchronization.

In other words, as the transmission belt is sheathed between the firstand second rotating shafts in the shape of figure 8, even if the firstrotating shaft rotates to a small arc, the second rotating shaft rotatesaccordingly to the small arc and vice versa.

As the transmission belt is sheathed between the first and secondrotating shafts in the shape of figure 8 for synchronous motion of thefirst and second rotating shafts, the two shafts rotate towards theopposite directions. Therefore, the solution can be used in theapplications requiring the rotation in the opposite directions duringthe synchronous motion of the first and second main bodies.

Therefore, for the technical solution in the embodiments of thisapplication, the transmission belt is sheathed between the first andsecond rotating shafts in the shape of a figure 8 to increase theinteraction between the transmission belt and the first and secondrotating shafts. The solution can enhance the technical effects ofsensitivity and fitness between the first and second rotating shaftsduring synchronization. Meanwhile, as the transmission belt in thetechnical solution is sheathed between the first and second rotatingshafts in the shape of figure 8, the solution can be widely used in theapplications requiring the rotation in the opposite directions duringthe synchronous motion of the first and second main bodies.

Optionally, a through-hole is further drilled on the transmission beltand a portion of the transmission belt runs through the through-hole toform the 8-shape.

A through-hole is arranged on the transmission belt and a portion of thetransmission belt constituting “8” shape runs through the through-holeto avoid two overlapped sections at the 8-shaped intersection with thewide transmission belt and expand the application scope of thetransmission belt.

Therefore, for the technical solution in the embodiments of thisapplication, a through-hole is drilled on the transmission belt and aportion of the transmission belt constituting the “8” shape runs throughthe through-hole to improve the convergent degree of the transmissionbelt, so the solution highlights the technical effects of improving thespace utilization efficiency of the rotating shaft.

Optionally, at least one convex tooth is arranged on the body of thefirst rotating shaft and/or the second rotating shaft;

The transmission belt is sheathed onto one convex tooth at least.

In the embodiments of this application, a punched hole can be arrangedon the transmission belt, corresponding to the convex tooth on the firstand/or second rotating shaft(s); when the first and/or second rotatingshaft(s) rotates, the convex tooth is dynamically inserted into thecorresponding hole on the transmission belt with the shaft rotation,like the chain motion mode for bicycle riding.

Without a doubt, the transmission belt can be free of perforation duringoperation, but take the tooth-groove mating mode to realize theengagement between the transmission belt and the shaft; in this case,the friction force increases between the transmission belt and the firstand second rotating shafts to get the synchronous effects.

Optionally, at least one recess hole is arranged on the body of thefirst rotating shaft and/or the second rotating shaft;

A convex pole is arranged on the transmission belt, corresponding to atleast one recess hole, and the convex pole can be inserted into thecorresponding recess hole during transmission.

During operation, a convex pole is further arranged on the transmissionbelt while one mating recess hole or groove is arranged on the firstand/or second rotating shaft(s) to realize the engagement between thetransmission belt and the shaft; in this case, the friction forceincreases between the transmission belt and the first and secondrotating shafts to get the synchronous effects.

Optionally, at least one shaft tooth is arranged on the body of thefirst rotating shaft and/or the second rotating shaft;

A belt tooth is arranged on the transmission belt, corresponding to atleast one shaft tooth, and the belt tooth is engaged with thecorresponding shaft tooth during transmission.

During operation, at least one belt tooth is further drilled on thetransmission belt and the shaft teeth corresponding to one or more beltteeth on the transmission belt are arranged on the first and/or secondrotating shaft(s) so that at least one belt tooth is engaged with thecorresponding shaft tooth in a teethed engagement pattern duringsynchronization; in this case, the friction force increases between thetransmission belt and the first and second rotating shafts to get thesynchronous effects.

In other words, for the technical solution in the embodiments of thisapplication, a convex gear and its mating structure can be furtherarranged respectively on the transmission belt and the shaft so that thetransmission belt is engaged with the shaft and the solution can validlyincrease the friction force between the transmission belt and the shaftto improve the technical effect of synchronous sensitivity.

Therefore, for the technical solution in the embodiments of thisapplication, a convex gear and its mating structure can be furtherarranged respectively on the transmission belt and the shaft so that thetransmission belt is engaged with the shaft for synchronization betweenthe first and second rotating shafts; therefore, the solution canvalidly increase the friction force between the transmission belt andthe shaft to improve the technical effect of synchronous sensitivity.

Optionally, at least one groove is arranged on the body of the firstrotating shaft and/or the second rotating shaft;

The transmission belt is sheathed in at least one groove.

In the case that the transmission belt is sheathed in the groove,because the transmission belt can be fixed by both edges into the grooveto prevent the belt from slipping away when the belt actuates thesynchronous motions of the first and second rotating shafts, thesolution has the technical effects of validly reducing the faultpossibility of the rotating shaft in this application.

During operation in the embodiments of this application, it is possibleto arrange the grooves only on the first rotating shaft. It is furtherpossible to arrange the grooves only on the second rotating shaft.Without a doubt, the grooves can be arranged on the first and secondrotating shafts at the same time. When multiple grooves are arranged onthe first and second rotating shafts, the transmission belt can be onlysheathed in one or more grooves. The arrangements depend on demandsduring operation.

Therefore, for the technical solutions in the embodiments of thisapplication, at least one groove is arranged on the first and/or secondrotating shaft(s) and the transmission belt is sheathed in one groove atleast to fix the belt between the first and second rotating shafts, orthe transmission belt may slip away leading to invalidity when the beltactuates the synchronous motions of the first and second rotatingshafts; and the solution has the technical effects of validly reducingthe fault possibility of the rotating shaft in this application.

Optionally, at least one groove is a spiral groove running around theshaft.

As the spiral groove is applied, the transmission belt sheathed in thespiral groove can shape a bigger torque onto the shaft during rotationof the first and/or second rotating shaft(s). Therefore, the forceapplied on the transmission belt decreases when the first and/or secondrotating shaft(s) rotates to the same radian.

For the technical solution in the embodiments of this application, atleast one groove can be a spiral groove around the shaft so that theforce applied on the transmission belt decreases with the technicaleffects of extending the rotating shaft service life when the firstand/or second rotating shaft(s) rotates to the same radian.

Optionally, the transmission belt is made of metal materials.

As metal materials have reliable resistance to tension and extremetemperature, metal parts are durable during operation, without anysubstantial deformation or performance change due to varied season andservice environment, not affecting the use of rotating shafts in thetechnical solutions herein.

Therefore, for the technical solution in the embodiments of thisapplication, the transmission belt can be made of metal materials withbetter resistance to tension and weather so as to get the technicaleffects of extending the service life and expanding the applicable scoperelated to the rotating shaft in this application.

The first main body is the connectionend of the display screen and the second main body is the systemconnection end. When the screen connection end relative to the firstrotating shaft rotates upward with the first rotating shaft as thecircle center of circler under the external force, the first rotatingshaft rotates resulting in reverse rotation of the second rotating shaftthrough synchronous actuation of the transmission belt. In other words,when the first rotating shaft rotates upward relative to the secondrotating shaft, the second rotating shaft rotates downward relative tothe first rotating shaft under synchronous actuation of the transmissionbelt. The first rotating shaft is connected to the screen connection endand the second rotating shaft is connected to the system connection endso that the connection ends of the screen and the system rotate towardsthe opposite directions. Therefore, users can realize the rotation ofthe screen connection end relative to the first or second rotating shaftonly with an external force, while the system connection end rotatestoward the opposite direction relative to the screen connection end andthe first or second rotating shaft under the synchronous action of thetransmission belt to get the effects of pulling the screen connectionend apart from the system connection end. Without a doubt, the users canget the rotation of the system connection end relative to the first orsecond rotating shaft only with an external force, while the screenconnection end rotates toward the opposite direction relative to thescreen connection end and the first or second rotating shaft under thesynchronous action of the transmission belt.
